Bulletin updated at 00:45 HKT 07/Jul/2017

Here is the latest weather bulletin issued by the Hong Kong Observatory.

A broad trough of low pressure affected the northern part of the South China Sea and the coast of Guangdong yesterday. An area of low pressure brought unsettled weather to the seas east of Taiwan. Locally, it was mainly cloudy with occasional showers and thunderstorms. About 20 millimetres of rainfall were generally recorded over the territory, rainfall even exceeded 40 millimetres over many places in the New Territories. The broad trough of low pressure will continue to bring showers and thunderstorms to the northern part of the South China Sea and the coast of Guangdong today and tomorrow.

Weather forecast for Hong Kong

Cloudy with showers and a few squally thunderstorms. Temperatures will range between 26 and 29 degrees. Moderate south to southeasterly winds, fresh at times offshore.

Outlook : There will still be showers and thunderstorms on Saturday. Showers will ease off with sunny periods early next week.


(The above forecast period is valid up to 23:59 HKT today, 07/07/2017; Regular update at : around 45 minutes past each hour, 16:15 HKT and 23:15 HKT)

Note

      

    1. From readings taken at various locations in Hong Kong during
the period 1987-2016, the background ambient gamma radiation
levels may vary between 0.06 and 0.30 microsievert per hour.

    2. The extent of health effects to a person as a result of
exposure to radiation is expressed by a physical quantity
called equivalent dose, in unit of sievert.  Protective
action may be required if there is an increase in the
ambient gamma dose rate above background such that the total
additional dose is expected to exceed 5000 microsieverts in
a relatively short period of time. For example, a dose of
5000 microsieverts may be reached when the ambient gamma
dose rate is 1000 microsieverts per hour (several thousand
times above background) and lasts for 5 hours.

    3. The readings of ambient gamma radiation level from
instrument are expressed in unit of gray, which is
numerically equal to the gamma dose expressed in sievert.
